Housed in a 20-TSSOP (4.40 mm width) with surface-mount leads. The supplier device package is also 20-TSSOP, so the land pattern is standard across the family. No oddball pitch or thermal pad to account for—just a straightforward SMD footprint that reflows without special handling.
The MAX3322EEUP+ supports a data rate of 250 kbps, which covers standard RS-232 speeds up to 115200 baud with headroom.
Yes, the supply range of 3V to 5.5V includes 3.3V, so it works directly with 3.3V logic without an external regulator or level translator.
